SUMMARY OF THE INVENTION Problems to be Solved by the Invention

An object of the present technology is to facilitate user's connection operation using a user interface screen.

Solutions to Problems

A concept of the present technology lies in

a connection control device that controls a connection between a source apparatus and a destination apparatus that are connected to a network, the connection control device including:

a display control unit that displays a first user interface screen for designating a predetermined combination of a source apparatus and a destination apparatus to operate the connection; and

a connection control unit that controls the connection between the source apparatus and the destination apparatus based on operation on the first user interface screen, wherein

on the first user interface screen, a first button is disposed in which a combination of a source apparatus and a destination apparatus is registered, and

the connection control unit executes control such that, when the first button of the first user interface screen is operated, the source apparatus and the destination apparatus of the combination registered in the first button are connected.

The present technology relates to a connection control device that controls a connection between a source apparatus and a destination apparatus which are connected to a network. For example, the connection control device is configured to include a personal computer, a tablet or the like connected to the network. By a display control unit, a first user interface screen is displayed for designating a predetermined combination of a source apparatus and a destination apparatus to operate a connection. This first user interface screen is displayed on, for example, a display unit of a monitor or a tablet connected to a personal computer. Then, a connection control unit controls the connection between the source apparatus and the destination apparatus based on operation on the first user interface screen.

On the first user interface screen, a first button is disposed, on which a combination of a source apparatus and a destination apparatus is registered. When the first button on the first user interface screen is operated, the connection control unit executes control so as to connect the source apparatus and the destination apparatus of the combination registered in this first button.

Thus, in the present technology, when the first button disposed on the first user interface screen is operated, a source apparatus and a destination apparatus of a combination registered in the first button are connected. Therefore, registering a desired combination in the first button enables a user to reliably execute operation of connecting the source apparatus and the destination apparatus of the combination with ease, simply by operating the first button, resulting in assistance to the user.

Note that, in the present technology, for example, on the first user interface screen, a second button in which a source apparatus is registered and a third button in which a destination apparatus is registered may be further disposed, and the connection control unit may execute control such that, when the second button and the third button are operated in succession, the source apparatus registered in the second button and the destination apparatus registered in the third button are connected.

Further, in the present technology, for example, the display control unit may further display a second user interface screen, on which a button disposed on the first user interface screen is edited. Thus, displaying a second user interface screen enables a user to edit a button disposed on the first user interface screen with ease.

In this case, for example, the second user interface screen may include a routing screen and an edit screen, on the routing screen, a plurality of source apparatuses may be disposed in one direction of a matrix and a plurality of destination apparatuses is disposed in the other direction, and on the edit screen, a button disposed on the first user interface screen may be created with reference to the routing screen. Thus, the second user interface screen includes an edit screen together with a routing screen, so that a user is allowed to create a button on the edit screen by simple operation such as drag and drop while referring to the routing screen.

Further, in this case, for example, when a cross point corresponding to a predetermined combination of a source apparatus and a destination apparatus of the routing screen is dragged and dropped to the edit screen, the first button, in which the predetermined combination is registered, may be created on the edit screen, when a predetermined source apparatus of the routing screen is dragged and dropped to the edit screen, the second button, in which the predetermined source apparatus is registered, may be created on the edit screen, and when a predetermined destination apparatus of the routing screen is dragged and dropped to the edit screen, the third button, in which the predetermined destination apparatus is registered, may be created on the edit screen.

Here, the edit screen may be provided with a button blank display part indicative of a button creation position as a position of the drag and drop. For example, when a button is created on the edit screen, the button blank display part to be provided on the edit screen may be provided at a position adjacent to the created button. Thus, providing a button blank display part on the edit screen enables indication, to a user, that a new button can be created, and also enables indication of a drop destination of drag and drop to a user.

Further, for example, when a cross point corresponding to a second combination of a source apparatus and a destination apparatus of the routing screen is dragged and dropped to the first button which is created on the edit screen and in which a first combination of a source apparatus and a destination apparatus of the routing screen is registered, the second combination may be further registered in the first button. In this case, a plurality of combinations can be registered in the first button with ease.

MODES FOR CARRYING OUT THE INVENTION

In the following, modes for carrying out the invention (hereinafter, referred to as “embodiment”) will be described. Description will be made in the following order.

-   1. Embodiment -   2. Modification Example

1. Embodiment

[Video System]

FIG. 1 shows a configuration example of a video system 10 in a broadcasting station as an embodiment. The video system 10 includes a source apparatus and a destination apparatus that are disposed in a studio 1, and a source apparatus and a destination apparatus that are disposed in a studio 2. Each apparatus is connected to a network in the broadcasting station. Here, the source apparatus is a video apparatus which outputs a video signal and corresponds to a video reproduction apparatus such as a camera, a VTR or the like. The destination apparatus is a video apparatus which receives a video signal and records or displays the signal, and which corresponds to a video recording apparatus such as a monitor, video server or the like.

In the studio 1, cameras 101 and 102, a video reproduction apparatus 103, monitors 104 and 105, a video recording apparatus 106, and a switching hub 107 are disposed. The respective apparatuses, i.e., the cameras, the video reproduction apparatus, the monitors, and the video recording apparatus, are connected to the switching hub 107 via a network cable. Additionally, in the studio 2, cameras 201 and 202, monitors 203 and 204, and a switching hub 205 are disposed. The respective apparatuses, i.e., the cameras and the monitors, are connected to the switch hub 205 via the network cable. Additionally, outside the studio 1 and the studio 2, a switching hub 301 is disposed, and the switching hub 107 in the studio 1 and the switching hub 205 in the studio 2 are connected to the switching hub 301 via the network cable.

Control of a connection between the source apparatus and the destination apparatus in the video system 10 is enabled by accessing the network in the broadcasting station from a connection control device. The connection control device is configured to include, for example, a personal computer or a tablet. In the illustrated example, in the studio 1, a tablet 108 handled, for example, by a cameraman or a director is shown. Additionally, in the illustrated example, in the studio 2, a tablet 206 handled, for example, by a cameraman or a director is shown. These tablets 108 and 206 are wirelessly connected to the network in the broadcasting station.

Additionally, the illustrated example shows a personal computer 302 which is connected to the external switching hub 301 outside the studio 1 and the studio 2 via the network cable and which is handled, for example, by a director. Additionally, the illustrated example shows, outside the broadcasting station, a personal computer 402 which is connected to the switching hub 301 via Internet 401 and which is handled, for example, by a director.

The connection control device (the tablet 108, 206, or the personal computer 302, 402) displays, in the monitor or a display unit, a user interface screen for designating a combination of an arbitrary source apparatus and a destination apparatus from a predetermined number of source apparatuses and destination apparatuses connected to the network in the broadcasting station, to operate a connection. Then, the connection control device executes control such that the source apparatus and the destination apparatus of the designated combination are connected based on the operation on the user interface screen.

FIG. 2 shows a configuration example of a personal computer 310 as a connection control device. Since a configuration of a tablet is substantially the same as a configuration of a personal computer, description thereof will be omitted.

The personal computer 310 has a Central Processing Unit (CPU) 311, a Read Only Memory (ROM) 312, a Random Access Memory (RAM) 313, a bus 314, an input/output interface 315, an input unit 316, an output unit 317, a storage unit 318, a drive 319, an Ethernet interface (Ethernet I/F) 320, and a network terminal 321. “Ethernet” is a registered trademark.

In the personal computer 310, the CPU 311, the ROM 312, and the RAM 313 are connected to each other via the bus 314. To the bus 314, the input/output interface 315 is further connected. To the input/output interface 315, the input unit 316, the output unit 317, the storage unit 318 and the drive 319 are connected.

The input unit 316 is configured to include a keyboard, a mouse, a microphone or the like. The output unit 317 is configured to include a display, a loudspeaker or the like. The storage unit 318 is configured to include a Hard Disk Drive (HDD), a non-volatile memory or the like. The drive 319 drives a removable media such as a magnetic disk, an optical disk, a magneto-optical disk, or a memory card. Additionally, to the bus 314, the Ethernet interface 320 is connected. To the Ethernet interface 320, the network terminal 321 is connected.

In the personal computer 310 shown in FIG. 2, the CPU 311 executes display control of the user interface screen by loading a program stored, for example, in the storage unit 318 into the RAM 313 via the input/output interface 315 and the bus 314 and executing the program. The CPU 311 also executes connection control of a source apparatus and a destination apparatus based on operation on the user interface screen. In this case, the CPU 311 configures the display control unit and the connection control unit. FIG. 3 shows a diagram of a functional configuration of the CPU 311. Specifically, the CPU 311 has a display control unit 311 a and a connection control unit 311 b.

[Control Panel Screen]

FIG. 4 shows an example of a control panel screen, which is displayed in the connection control device (the tablet 108, 206, or the personal computer 302, 402), and which is one of user interface screens for designating a predetermined combination of a source apparatus and a destination apparatus to operate a connection. As a control panel, a plurality of control panels is registerable. By operating a button indicated by an arrow 500 to select a desired control panel from a pull-down menu, the control panel can be called up. In the illustrated example, “Panel_0001” is called up. Additionally, this control panel screen can be zoomed on the screen by operating a lever indicated by an arrow 501.

Disposed on the control panel screen are a cross point (XPT) button (first button) indicated by an arrow 502, a source (SRC) button (second button) indicated by an arrow 503, and a destination (Dest) button (third button) indicated by an arrow 504. In the illustrated example, disposed as the cross point buttons are four buttons, namely, “XPT_01”, “XPT_02”, “XPT_03” and “XPT_04”. Additionally, disposed as the source buttons are four buttons, namely, “SRC_001”, “SRC_002”, “SRC_003” and “SRC_004”. Further, disposed as the destination buttons are four buttons, namely, “Dest_001”, “Dest_002”, “Dest_003” and “Dest_004”.

In the cross point (XPT) button, a combination (cross point) between a source apparatus and a destination apparatus is registered in advance. In the cross point button “XPT_01”, a combination of a source apparatus “CAM 1” and a destination apparatus “MONI 01”, and a combination of a source apparatus “CAM 2” and a destination apparatus “MONI 02” are registered. Additionally, in the cross point button “XPT_02”, a combination of the source apparatus “CAM 1” and a destination apparatus “MONI 03”, and a combination of the source apparatus “CAM 2” and a destination apparatus “MONI 04” are registered. Additionally, in the cross point button “XPT_03”, a combination of a source apparatus “CAM 5” and a destination apparatus “MONI 08” is registered. Further, in the cross point button “XPT_04”, a combination of a source apparatus “CAM 6” and a destination apparatus “MONI 07” is registered.

In the case of the cross point button in which only one combination is registered (i.e. “XPT_03” or “XPT_04”), every time the button is operated, alternate switching is performed between a first state in which the one combination enters an active state and a second state in which the same enters an inactive state. Additionally, in the case of the cross point button in which the plurality of combinations is registered (i.e. “XPT_01” or “XPT_02”), every time the button is operated, alternate switching is performed between a first state in which all the combinations enter the active state and a second state in which all the combinations enter the inactive state.

In the case of the cross point button in which the plurality of combinations is registered, there may be a third state in which only a part of the combinations enters the active state by being controlled by other connection control device. In a combination to enter the active state, a source apparatus and a destination apparatus of the combination are connected.

Here, a cross point button in which all the combinations are in the active state, a cross point button in which all the combinations are in the inactive state, and a cross point button in which only a part of the combinations is in the active state are set to be in display states different from one another.

For example, a cross point button in which all the combinations are in the active state has such a display state as shown by the cross point button (“XPT_01”), in which, for example, with a hue set by a user, chroma and luminance are increased and characters or the like indicating a combination are highlighted. Additionally, for example, a cross point button in which all the combinations are in the inactive state has such a display as shown by the cross point button (“XPT_03”, “XPT_04”), in which, for example, with a hue set by a user, chroma and luminance are reduced.

Additionally, for example, a cross point button in which only a part of the combinations is in the active state has such a display as shown by the cross point button (“XPT_2”), which is an intermediate display state. For example, it is set to be a hatching state in which high chroma and luminance parts and low parts are alternately arranged. Alternatively, although not shown in the figure, an upper half may be a high chroma and luminance part and a lower half may be a low chroma and luminance part.

FIGS. 5(a) to 5(c) show an example of a behavior of a cross point button in which a plurality of combinations is registered. Here, the cross point button “XPT_02” is currently in operation. When the button is operated in the second state in which all the combinations are in the inactive state as shown in FIG. 5(c), the button enters the first state in which all the combinations are in the active state as shown in FIG. 5(b). Additionally, when the button is operated in this state, the button enters the first state in which all the combinations are in the inactive state as shown in FIG. 5(c). Additionally, when the button is operated in the third state in which only a part of the combinations is in the active state as shown in FIG. 5(a), the button enters the first state in which all the combinations are in the active state as shown in FIG. 5(b).

Returning to FIG. 4, in each source (SRC) button, a source apparatus is registered in advance. Additionally, in each destination (Dest) button, a source apparatus is registered in advance. When a source button and a destination button are operated in succession, the source apparatus and the destination apparatus registered in these buttons are connected in a paired state. Thus, in each of the paired buttons, a button name (apparatus name) of each partner side is displayed.

FIGS. 6(a) to 6(c) show an example of behaviors of the source buttons and the destination buttons. As shown in FIG. 6(a), it is assumed that, as a destination button to which a source button is to be assigned, a destination button “Dest_001” is operated. At this time, as shown in FIG. 6(b), a display mode of the destination button “Dest_001” changes to enter, for example, a depressed state. Additionally, in this process, when there exists a source button being in the paired state with the destination button “Dest_001”, the source button enters, for example, a light emission state. In the illustrated example, a source button “SRC_002” enters the light emission state.

In this state, when a source button “SRC_001” is operated as shown in FIG. 6(b), the source button “SRC_001” and the destination button “Dest_001” are paired, so that apparatuses registered therein enter a connection state. Then, at this time, the source button “SRC_001” and the destination button “Dest_001” enter, for example, the light emission state to show that the buttons are paired as shown in FIG. 6(c).

Note that, in this step, only one source button can be paired with one destination button and, therefore, paring between the destination button “Dest_001” and the source button “SRC_002” is cancelled.

Also FIGS. 7(a) to 7(c) show an example of behaviors of the source buttons and the destination buttons. It is assumed that, as a source button to which a destination button is to be assigned, the source button “SRC_001” is operated as shown in FIG. 7(a). At this time, as shown in FIG. 7(b), a display mode of the source button “SRC_001” changes to, for example, the depressed state.

When the destination button “Dest_001” is operated in this state as shown in FIG. 7(b), the destination button “Dest_001” and the source button “SRC_001” are paired, so that apparatuses registered therein enter the connection state. Then, at this time, the source button “SRC_001” and the destination button “Dest_001” enter, for example, the light emission state to show that the buttons are paired as shown in FIG. 7(c). Note that, in this step, pairing between the destination button “Dest_001” and the source button “SRC_002” having been in paired state is cancelled.

[Edit Control Panel Screen]

FIG. 8 shows an example of an edit control panel screen which is displayed in the connection control device (the tablet 108, 206, or the personal computer 302, 402) and which is one of the user interface screens. The edit control panel screen simultaneously includes a routing screen indicated by an arrow 601 and an edit screen indicated by an arrow 602. The routing screen is disposed on the upper side of the edit control panel screen and the edit screen is disposed on the lower side of the edit control panel screen. The arrangement of these screens is not limited to this example.

The routing screen is a screen for selection of a desired combination of a source apparatus and a destination apparatus, selection of a source apparatus, selection of a destination apparatus, and the like. The routing screen is provided for each work group. By operating a button indicated by an arrow 603 to select a desired work group from a pull-down menu, a routing screen for the work group can be called up. In the illustrated example, “Workgroup_0001” is selected. Additionally, the routing screen can be zoomed on the screen by operating a lever indicated by an arrow 604.

On the routing screen, a plurality of source apparatuses and a plurality of destination apparatuses is disposed in matrix. Specifically, on the routing screen, the plurality of source apparatuses is horizontally disposed in an upper part, as indicated by an arrow 605. In this case, each source apparatus is displayed as an icon, and an apparatus name and the like can be displayed as well. The icon can be replaced by an arbitrary image prepared by a user.

Additionally, on the routing screen, as indicated by an arrow 606, a plurality of destination apparatuses is vertically aligned in a right part. In this case, each destination apparatus is displayed as an icon, and an apparatus name and the like can be displayed as well. The icon can be replaced by an arbitrary image prepared by a user.

The edit screen 602 is a screen for editing buttons (the cross point buttons, the source buttons, the destination buttons) disposed on the edit control panel screen. On the edit screen, as indicated by an arrow 607, rectangular button blank display parts each indicative of a button creation position are displayed by broken lines. In a state where no button is created on the edit screen, only one part is displayed, for example. Additionally, after a button is created, such a state, as shown in the figure, is attained in which a plurality of button blank display parts is displayed so as to surround the created button. Note that, a position and the number of button blank parts displayed are not limited to those in this example.

As indicated by an arrow P1, when a cross point (intersection) corresponding to a predetermined combination of a source apparatus and a destination apparatus on the routing screen is selected and the cross point is dragged and dropped to the button blank display part of the edit screen, a cross point button in which the predetermined combination is registered is created on the edit screen.

When a drop destination to which such a cross point is dragged and dropped is a cross point button already created on the edit screen, the combination of the source apparatus and the destination apparatus is added to this cross point button. This enables a cross point button to have a plurality of combinations of source apparatuses and destination apparatuses registered.

Additionally, on the routing screen, a plurality of cross points can also be selected by successive clicks. When the plurality of cross points is dragged and dropped to the button blank display part on the edit screen, a cross point button in which the plurality of the combinations of the source apparatuses and destination apparatuses are registered is created on the edit screen.

Additionally, as indicated by an arrow P2, when a predetermined source apparatus on the routing screen is selected and the source apparatus is dragged and dropped to the button blank display part of the edit screen, a source button in which the predetermined source apparatus is registered is created on the edit screen. Further, as indicated by an arrow P3, when a predetermined destination apparatus on the routing screen is selected and the destination apparatus is dragged and dropped to the button blank display part on the edit screen, a destination button in which the predetermined destination apparatus is registered is created on the edit screen.

When a button created on the edit screen is selected, a corresponding part of the routing screen corresponding to the button enters a selected state. In other words, a display mode of the corresponding part is to indicate the selected state, though the state is not shown. For example, when a cross point button created on the edit screen is selected, a cross point corresponding to a combination of a source apparatus and a destination apparatus registered in the cross point button enters the selected state. Additionally, for example, when a source button created on the edit screen is selected, a source apparatus registered in the source button enters the selected state. This enables a user to confirm what is registered in the button created on the edit screen.

An operation button indicated by an arrow 608 is a shift operation button for up-and-down and right-and-left movements in order to shift a button created on the edit screen. After a predetermined button is selected on the edit screen, operation of this shift operation button results in shifting the position of the predetermined button. After a predetermined button is selected on the edit screen, dragging and dropping the predetermined button also enables to shift the position of the predetermined button.

When a drop destination is the button blank display part, the predetermined button is moved to the button blank display part. In this case, the original position of the predetermined button turns to be, for example, the button blank display part. Additionally, when a drop destination is a position of other button, the predetermined button is moved to the position of that other button. In this case, that other button is moved to the predetermined button position. In other words, in this case, the positions of the predetermined button and that other button are exchanged.

An operation button indicated by an arrow 609 is a horizontal separator setting button for setting a separator extending in a horizontal direction, which partitions the edit screen for a button created on the screen. Selecting the horizontal separator setting button and dragging and dropping the same to the edit screen results in setting the horizontal separator at the drop destination. In this case, a length of the horizontal separator is automatically adjusted so as to cover a range of the created button.

An operation button indicated by an arrow 610 is a vertical separator setting button for setting a separator extending in a vertical direction, which partitions the edit screen for a button created on the screen. Selecting this vertical separator setting button and dragging and dropping the same to the edit screen results in setting the vertical separator at the drop destination. In this case, a length of the vertical separator is automatically adjusted so as to cover a range of the created button.

In a state where the button blank display part on the edit screen is selected, operation of “Create New” button indicated by an arrow 611 results in creating a new button in the button blank display part. Properties of the thus created new button can be set on a property setting screen indicated by an arrow 612. In a state where a predetermined button of the edit screen is selected, properties of the button can be set on the property setting screen. On the property setting screen, a background color or a background image of each button can be set as well. A background image of a button can also be replaced by an arbitrary image prepared by a user.

In a state where a predetermined button of the edit screen is selected, operation of “Delete” button indicated by an arrow 613 results in deleting the predetermined button. Additionally, operation of “Revert” button indicated by an arrow 614 results in deleting all the buttons created on the edit screen. Additionally, operation of “Apply” button indicated by an arrow 615 results in registering each button created on the edit screen in a called control panel.

[Session List Screen]

FIG. 9 shows an example of a session list screen which is displayed in the connection control device (the tablet 108, 206, or the personal computer 302, 402) and which is one of the user interface screens for designating a combination of an arbitrary source apparatus and a destination apparatus to operate a connection. This session list screen is a most primitive screen on which a source apparatus and a destination apparatus are displayed in a list to select a cross point (intersection).

This session list screen is provided for each work group. By operating a button indicated by an arrow 800 to select a desired work group from a pull-down menu, a session list screen for the work group can be called up. In the illustrated example, a “Workgroup_0001” is selected.

As indicated by an arrow 801, in an upper left part of the screen, lists of source apparatuses and destination apparatuses connected to the network are displayed, respectively. After selecting a combination of a source apparatus and a destination apparatus from the list, operation of “Registration” button indicated by an arrow 802 enables registration of the combination. Based on the registration, a connection between the source apparatus and the destination is controlled.

A display indicated by an arrow 803 represents combinations of source apparatuses and destination apparatuses registered. After one of the combinations of registered source apparatuses and destination apparatuses is selected, operation of “Call” button indicated by an arrow 804 enables the combination to be called up to the list. The right side of the screen is being currently active, i.e. the combination of the connected source apparatus and destination apparatus is displayed as indicated by an arrow 805.

FIG. 10 shows an example of a topology map screen which is displayed in the connection control device (the tablet 108, 206, or the personal computer 302, 402) and which is one of the user interface screens. This is a screen that enables a use to view, on one screen, connection state of the network and a load imposed on each terminal. This example shows a case where the network is configured to include a plurality of cameras as source apparatuses, one monitor as a destination apparatus and two switching hubs (network switches).

As indicated by an arrow 900, corresponding to each terminal at input/output of the switching hub, a load display part is provided in which a load of each terminal is indicated by a height of piled bars (e.g. green bars). A user is allowed to read a current connection state of the network on the topology map screen. Additionally, the user is allowed to read a load state of each terminal at input/output of the switching hub on the topology map screen.
